방사성 폐기물 내 59/63Ni 정량을 위한 분리
Separation for the Determination of 59/63Ni in Radioactive Wastes
Abstract
A study on the separation of in various radioactive wastes discharged from nuclear power plants has been performed for a use in their quantification which is indispensible for the evaluation of the radionuclide inventory Ni was recovered along with Ca, Mg, Al, Cr, Ti, Mn, Ce, Na, K, and Cu through the sequential separation procedure of Re(as a surrogate of ), Nb, Fe and Sr by anion exchange and Sr-Spec extraction chromatography. In this research, chemical separation of Ni from the co-existing elements was investigated by cation exchange and Ni-Spec extraction chromatography. Precipitation behaviour of Ni and the co-existing elements with dimethylglyoxime(DMG) was investigated in ammonium and tartaric in order to purify separated Ni fractions and to prepare source for the radioactivity measurement using a gas proportional counter. Recovery of Ni separated through ion exchange chromatographic separation procedure was with relative standard deviation of . In addition, recovery of Ni with DMG in the tartaric was with relative standard deviation of .
